The MQS codec isn't an i2c device, so use of_find_device_by_node

Because MQS only support playback, then add a new audio map.
And there maybe "model" property or no "audio-routing" property in

This patch introduces a new ioctl for vhost-vdpa device that can
report the iova range by the device. For device that depends on
platform IOMMU, we fetch the iova range via DOMAIN_ATTR_GEOMETRY. For
devices that has its own DMA translation unit, we fetch it directly
from vDPA bus operation.
This patch implements get_iova_range method for vdpa_sim. Since
vdpa_sim is a software device, simply advertise a [0ULL, ~0ULL] range.

The log of 'make ARCH=m68k clean' does not look nice.
$ make ARCH=m68k clean
CLEAN arch/m68k/kernel
[ snip ]
CLEAN usr
rm -f vmlinux.gz vmlinux.bz2
CLEAN vmlinux.symvers modules.builtin modules.builtin.modinfo
Use CLEAN_FILES to simplify the code, and beautify the log.

In 2019, we introduced pin_user_pages*() and now we are converting
get_user_pages*() to the new API as appropriate. [1] & [2] could
be referred for more information.

Add F_MMU_IN_ORDER_WR_EN definition in MISC_CTRL.
In order to improve performance, we always disable STANDARD_AXI_MODE
and IN_ORDER_WR_EN in MISC_CTRL.
Change since v3:
1. Rename Disable STANDARD_AXI_MODE in MISC_CTRL to Set MISC_CTRL register
2. Add F_MMU_IN_DRDER_WR_EN definition in MISC_CTRL
For mt6779, MMU_INV_SEL register's offset is changed from
0x38 to 0x2c, so we can put inv_sel_reg in the plat_data to
use it.
In addition, we renamed it to REG_MMU_INV_SEL_GEN1 and use it
before mt6779.
Change since v3:
1. Fix coding style

This patchset adds mt6779 iommu support.
mt6779 has two iommus, they are MM_IOMMU(M4U) and APU_IOMMU which used ARM
Short-Descriptor translation format.
The mt6779's MM_IOMMU-SMI and APU_IOMMU HW diagram is as below, it is only a
brief diagram:
EMI
The max larb number that a iommu HW support is 8(larb0~larb7 in the below
diagram).
If the larb's number is over 8, we use a sub_common for merging
several larbs into one larb. At this case, we will extend larb_id:
bit[11:9] means common-id;
bit[8:7] means subcommon-id;
From these two variable, we
Some platforms(ex: mt6779) have a new register called by REG_MMU_WR_LEN
to improve performance.
This patch add this register definition.

1. Start from mt6779, INVLDT_SEL move to offset=0x2c, so we add
REG_MMU_INV_SEL_GEN2 definition and mt6779 uses it.
2. Change PROTECT_PA_ALIGN from 128 byte to 256 byte.
3. For REG_MMU_CTRL_REG register, we only need to change bit[2:0],
others bits keep default value, ex: enable victim tlb.
For iommu offset=0x48 register, only the previous mt8173/mt8183 use the
name STANDARD_AXI_MODE, all the latest SoC extend the register more
feature by different bits, for example: axi_mode, in_order_en, coherent_en
and so on. So rename REG_MMU_MISC_CTRL may be more proper.

This patch adds description for MT6779 IOMMU.
MT6779 has two iommus, they are mm_iommu and apu_iommu which
both use ARM Short-Descriptor translation format.
In addition, mm_iommu and apu_iommu are two independent HW instance
, we need to set them separately.

First, when memory allocation for sg_list_unaligned failed, there
is no point of calling put_pages() as we haven't pinned any pages.
Second, if get_user_pages_fast() failed we should unpinned num_pinned
pages, no point of checking till num_pages.
This will address both.

Nowadays some embedded systems use VCOM to transfer large log and data.
Take LTE MODEM as an example, during the long debugging stage, large
log and data were transfer through VCOM when doing field try or in
operator's lab. Here we suggest slightly increase the transfer buffer
in u_serial.c for
